Boron carbide (B₄C) has emerged as a transformative material in extreme industrial environments due to its unparalleled combination of hardness (Mohs 9.5+), lightweight properties (density 2.52 g/cm³), and chemical inertness[1][7]. In oil drilling and mining operations, these characteristics make boron carbide products indispensable for enhancing equipment durability, operational efficiency, and safety. This article explores their critical applications across both industries.
